Product details

Its two normally-open instantaneous contacts handle 10 A at 24 V, with a surge voltage resistance of 6 kV — enough isolation for most 24 VDC control loops in a panel. The contact reliability spec of one incorrect switching operation per 100 million operations at 17 V, 1 mA means it is trustworthy for PLC input dry-contact feedback even at low signal levels.

Fastens via screw and snap-on mounting onto a DIN rail — the S00 footprint is 45 mm wide, 57.5 mm tall, and 72 mm deep. The mounting position is flexible: +/-180° rotation on a vertical surface, and can be tilted forward/backward by +/-22.5°. Accepts solid wire from 0.5 to 4 mm² — spring-cage or screw terminals depending on variant, but this order code uses screw-type.

Rated for operation from -25 to +60 °C, storage and transport from -55 to +80 °C. Shock resistance is 10 g for 5 ms and 5 g for 10 ms — fine for normal industrial vibration but not heavy hammering.

Frequently asked questions

What are the key ratings for this auxiliary contactor?

It has 2 instantaneous NO contacts, rated 10 A at 24 V, with a surge voltage resistance of 6 kV. The contact reliability is one failure per 100 million operations at 17 V, 1 mA.

What is the physical size and mounting?

The S00 frame is 45 mm wide, 57.5 mm tall, and 72 mm deep. It mounts via screw and snap-on to a DIN rail, with flexible orientation. Accepts solid wire 0.5–4 mm².

What compliance documentation is available?

The RoHS substance prohibition date is 07/01/2006. The part carries IP20 protection on the front and is rated for pollution degree 3.
